[Bug 422035] Re: Syslog fills up with generic-usb "control queue full"

[hoppy]

I can confirm problems with this in Ubuntu 2.6.32-22.33-generic
2.6.32.11+drm33.2.

The message (generic-usb 0003:051D:0002.0005: control queue full) is
repeated every 10 seconds.

It seems to result after a while in my usb mouse freezing, although
keyboard still works. Attempting to logout or shutdown results in the
system hanging and requiring a hard reboot.

I have a APC UPS connected to the usb  and am using apcupsd to monitor
it. If I kill apcupsd the messages stop and the mouse freeze does not
occur.

Restarting apcupsd results in around 80 of the messages printed in the
syslog at the same time.

Soon after restarting apcupsd I get the following if it's any help:
